UNITED STATES FRANK W. DE LUCHI, OF OAKLAND, CALIFORNIA.

ELECTRIC HEATER.

Application ined February 13, 1922.

To all whom it may concern.'

Be it known that I, FRANK W. DE LUCHI, a citizen ot' the United States, residing at Oakland, in the county ot Alameda and State ol California, have invented certain new and useful Improvements in Electric Heaters, of which the following is a specification.

My invention is an electric heater' constructed with air circulating means through which the air of the room is circulated whereby the room is etliciently heated..

Referring to the annexed drawings in which my invention is illustrated and which forms a part of this specification:

Figure l is a vertical section ot' one term ot' my heater.

Figure 2 is a vertical section of another form of my heater.

Figure 3 is a vertical section of another form ot' my heater.

Figure 4 is a vertical section ot' another' form ot' my heater.

Inl the form of my invention shown in Figure 1 there is a heating chamber 1 which is suspended in the floor or' the room between the floor and the ceiling of the room below, the top of which chamber is covered with a perforated wall or grid 2 which rests on the floor over the chamber. The chamber may be lined with a lining of asbestos 3. An electric heating element 4 is suspended in the chamber 1 by means ot hooks 5, 6 and 7 secured to said element and binding posts 8 and 9 and pins 10 projecting inwardly from the vertical wall of said chamber, the hooks 5 and 6 engaging the binding posts 8 and 9 and the hooks 7 engaging the pins 10. An air duct 11 extends between the floor and the ceiling below, one end ot said duct communicating with the room through the floor at a distance Afrom the chamber 1 and the other-end of said duct communicating with the bottom of said chamber. A perforated plate or grid 12 rests on the floor over the end of the duct 11 which communicates with the room.

Cold air enters the duct l1 from the room and passes through the chamber 1 where it is heated and passes out of the top of the chamber back into the. room, thus providing a circulation of the air through the room and the heater and efficiently heating the room.

ln the iorm oic my invention shown in Serial N'o. 536,173.

Figure 2 a chamber 2O is suspended in and below the floor and a heating chamber 21 ,is lsuspended within the chamber from a grid 22 which rests upon the oor over the clnrmber 20. The chamber 21 is open at the bottom and top and a vertical cold air inlet duct 23 is provided between the vertical wall ot said chamber and the chamber 20 which duct communicates at its upper end with the room through the grid 22 and at its lower end wit-h the lower end of the chamber 2l. Binding posts 24 and 25 project inwardly from the vertical wall of the chamber' 20 into the chamber' 21 through the vertical slotted walls of said chamber, the slots in said walls extending upwardly from the lower edge of said wall to allow the chamber 21 to be lowered over said binding posts. Pins 26 project inwardly from the vertical wall of the chamber 21. An electrical heating element 27 is suspended within the heating chamber 21 by hooks 28, 29 and 30, the hooks 28 and 29 engaging the binding posts 24 and 25 and the hooks 30 engaging the pins 26.

Cold air enters the duct 23 through the grid 22 and passes into the bottom of and through the chamber 21 and grid 22 and is heated by element 27.

In the modified form of my invention shown in Figure 3 a heating chamber 30 is mounted in the wall of the room a short distance above the floor and communicates with the room through a grid 31 which rests against the wall and forms the outer wall ot' the chamber. with an inlet 32 in the bottom thereof which communicates with the upper end of a duct 33m the wall below the chamber, the lower end ot said duct communicating with a cold air inlet 34 in the lower part ot the wall. A grid 35 rests against the wall over the inlet 34. An electric heating element 3Gy is mounted in thel chamber 30.

Cold air enters the duct 33 through inlet 34 and passes through the casing 3() where the air is heated by heating element 36 and passes through grid 31 into the room.

My heater shown in Figure 4 is a portable or electric stove heater' comprising a casing 40 and an electric heating element 41 mounted in said casing, the lower end of the casing having cold air inlets 42 and the top of the casing being covered with a grid 43. The casing 4() may be mounted on legs 44. Handles may be secured on the sides olf Said chamber is provided the casing for carrying the heater about 'it'roin place to pl ace. A

Having described my invention, l claim: l. in electric heater comprising a heating chamber provided with an air inlet and an outlet, binding posts mounted in the Valls t l'icating element. v

2. An electric heater inciiidii'ig a hcatiiig'` chamber provided with :in inlet and an outlet.y pine andbii'iding posts secured 'to the Wallis ci said chamber, an eiciftricheating element, and hooks en said heating` element, certain oi? said hooks engaging Said pins and the other hooks ei'ie'aging Said binding posts :ind- Suspendii'ig Seid heating element 'Within Said heating chamber, the 'hooks engaging Said binding posts forming the conductore between Saidv ljiinding poete and the coil of eaidheating element.
